Fecundity determines the outcome of founding queen associations in ants.

ABSTRACT: Animal cooperation evolved because of its benefits to the cooperators. Pleometrosis in ants-the cooperation of queens to found a colony-benefits colony growth, but also incurs costs for some of the cooperators because only one queen usually survives the association. While several traits in queens influence queen survival, they tend to be confounded and it is unclear which factor specifically determines the outcome of pleometrosis. In this study, we used the ant Lasius niger to monitor offspring production in colonies founded by one or two queens. Then, we experimentally paired queens that differed in fecundity but not in size, and vice versa, to disentangle the effect of these factors on queen survival. Finally, we investigated how fecundity and size differed between queens depending on wh
